- Given: (0, 3.0), (2, 20.6), (4, 72.8), (6, 236.5), (8, 714.0), (10, 2209.7) Use the regression feature of a graphing utility to find an exponential model y ab* for the data and identify the coefficient of determination. (Enter coefficients to four decimal places.) ywA regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y). The results of the regression were: y-ax+b a=-1,263 b=21.291 12-0.5776 r=-0.76 Use this to predict the number of situps a person who watches 5 hours of TV can do (to one decimal place)If ? = 1.602×10!!"?, calculate the value of h from the slope (include the unit). The slope is = -7.94x10^13 and the intercept is = 8.21x10^14
